[Acute torsion of the greater omentum: a case report].

Taking as their starting point a case of greater omental torsion recently observed in their surgical department, the authors carefully review the relevant literature data and the aetiological, pathogenetic, clinical and diagnostic aspects which make this rare disease hard to identify preoperatively. They stress that resorting to laparotomy is a rational course of action even if laparoscopy today constitutes an effective diagnostic and therapeutic option.
